This invention relates to typing copy sets which consist of letter orform sheets and interleaved sheets of carbon paper or the like in whichthe paper sheets forming one set are detachably united with each otherto form a block, and in particular to a form of construction of thetyping copy set or block of this kind in which the individual sets orblocks are united along one edge, preferably along the lower edge of oneset and the upper edge of the next succeeding set. v

The Writing of a number of letter or form sheets with the same text issubstantially simplified by the employment of typing copy sets. Thesegenerally consist of a series of writing and carbon paper sheetsarranged in alternate sequence. The writing sheets of one set are, inorder that they shall always lie accurately superposed, usually joinedtogether at their upper transverse edges by gluing, stapling or thelike. The interleaved sheets of carbon paper project at one free edgefrom the block of the writing paper sheets so that they may be quicklyremoved from the Writing paper sheets after the text has been written.

In order to save time consuming work in clipping each individual set offorms into the typing or book-keeping machine these sets are alsoarranged to form long strips of paper, the lower transverse edge of oneset being detachably connected with the upper edge of the next followingset in each strip. The series of successive sets are generally suppliedand employed assembled in zig-zag fashion and may be readily separatedfrom each other by means of a heavy perforation or the like extendingthrough all the sheets.

Even with this arrangement in sequence of the typing copy sets aconnection between the superimposed sheets is desirable in ordereffectively to prevent relative longitudinal displacement of the sheetswith irregular feeding in the typewriter or book-keeping machine or thelike. The connection of the individual papers, sheets or strips employedhitherto in various forms of construction presents however, a number ofdisadvantages.

The invention, which has for its object to avoid the disadvantages ofthe typing copying sets employed hitherto with alternating Writing andcarbon paper sheets, arranged in sequence at their transverse edges,consists in that the first and last writing sheet of each set has ateach of its two longitudinal edges a special strip or extension, thisstrip being connected at one edge with corresponding strips of the otherwriting sheets, arranged on one side only, and at the opposite edge withthe part of the carbon paper sheets projecting from the block of thewriting sheets, the connection being made in any suitable manner,preferably by gluing or the like.

According to the invention the fixing strips are detachably formed atthe edges of all the writing sheets, for example with a perforationgoing through all sheets or with superimposed perforations.

The individual sets can be very rapidly and simply taken apart aftertyping and separation from the assembled strip, in the case of a stripof successively arranged typing atent copy sets constructed in themanner described. It is necessary for this purpose only to tear off thestrips of the first and last writing sheet at the fixing edge for thecarbon paper along a perforation whereby all the carbon papers aresimultaneously separated from the paper sheets. The writing sheets arethen still connected with each other through the fixing strip at theother edge and can be separated by tearing away this strip also.

The connection of the superimposed sheets of writing and carbon papersalong the lateral fixing strips can be effected in various ways. Thegluing preferred in accordance with the invention is advantageous sincein this way the lateral edges of the block have a uniform thickness sothat the passage of the sets through the typing or bookkeeping machineis not hindered. Moreover at the left hand and the right hand edge thereare, apart from the,

first and last writing sheets only the superimposed copy or carbon papersheets, i. e. practically only half as many sheets as in the middle partof the strip of sets of forms.

A further characteristic of the invention consists in connecting thesuperimposed fixing strips by means of staggered points secured withglue or the like in such a way that in longitudinal sequence the firststrip is glued at intervals to the second and then the second with thethird and so on.

The drawing illustrates an example of construction of the invention.

Figure 1 shows in vertical plan a portion of a strip consisting of anumber of sets of forms arranged in sequence, each set consisting offive sheets of writing paper and four sheets of carbon paper alternatingtherewith. Figure 2 is a transverse sectional view of Figure 1. In orderto illustrate the relation between the various strips these are madevisible at the lower edge, each strip being made somewhat shorter thanthe immediately following strip.

Of the writing paper sheets a to a the first, a as well as the last, aare provided at both longitudinal edges with fixing strips b. Theinterposed writing paper sheets a,, a 41,, merely have correspondingfixing strips at the left hand edge only. The carbon paper sheets c, to0 extend at the right hand edge in a part which is preferably notcoated, with which they engage between the fixing strips b at the righthand edge of the writing paper sheets a,, a

The fixing strips 11 on the writing paper sheets a to a are limited by aperforation d and are therefore capable of being readily removed bythemselves. Similarly the individual sets may be readily removed fromthe strip by tearing along the transverse perforation e. All thesuperimposed fixing strips and the uncoated lateral edges of the carbonpaper sheets are united the one with the other by continuous orintermittent gluing g. By removing the carbon paper sheets from thewriting paper sheets, none of the latter are loosened because toseparate the carbon paper sheets, it is necessary to tear off but twostrips of the cover sheets. On the other hand, to separate the writingsheets from the assembly, it is necessary to tear off as many strips asthere are writing sheets in the manifold. Since the number of writingpaper sheets in the manifold is always greater than the number of carbonsheets, it will be seen that, on pulling the strips to which the carbonpapers are connected, they only will be separated, and the writing papersheets will remain attached to one another.

After the writing and separation of an individual set the sheets ofcarbon paper may be readily removed by simply tearing off the first andlast writing sheets of the right hand fixing strips. The sheets ofwriting paper can be separated from each other by tearing off the lefthand strip. Thus, it will be seen that copying sets are providedarranged like chains in a row. Consequently, the type- 3 writer andbooking rnachine does not require any special studs, cogs, or the likefor guiding the sheets. In other words, the sheets are guided in theconventional manner by the smooth rollers of the typewriter with theresult that no special typewriter or machine will be required for thisoperation. To obtain these desired objects, the sheets are provided atthe left hand with a projecting end portion or margin and the carbonpapers with a projecting portion or margin at the right hand, which areglued to gether as at g shown in Figure 2. Thus, it will be seen thatonly the first and last sheets have projecting margins at both sides. Bythis arrangement, about half as many sheets are placed on each other atboth end portions or margins than at the intermediate or centralportions of the sets.

It will be noted that the improved manifold assembly among otherfeatures includes arranging the strips d along one adjacent longitudinaledge of the top and bottom writing sheets and the strips of theintermediate sheets superimposed and secured to each other. The width ofthe writing paper sheets between the cover sheets terminating short ofthe marginal strips at the other lo'ngitudinal edges of the top andbottom sheets so as to provide free end portions. The carbon papersheets are of substantially the same width as the intermediate writingpaper sheets and extend from the longitudinal edges of the cover sheetson the side of the manifold assembly o'pposite a longitudinal edge ofthe adjacent marginal strips so as to provide free end portions. Thestrips along the other adjacent longitudinal edges of the top and bottomwriting sheets and the adjacent marginal portions of the carbon sheetsare superimposed and secured to each other. Thus, it will be seen thatthe parts are constructed and arranged so that the carbon paper sheetsremain attached to the adjacent detachable strips when the latter isseparated from the Writing paper sheets. Further, "the writing papersheets also remain attached to one another so that in a single operationthe manifold assembly may be separated in two units, one of whichincludes all the writing paper sheets and the other all the carbon papersheets.
